Displaying Statistics For a Single Port
There are several reasons why the EPICenter server may not be able to display any device
data:
• TheEPICenterservercannotcommunicatewiththedevice(indicatedby an“S”inared
circle next to the device name).
• The device does not have RMON enabled, or RMON was just recently enabled and no
data samples exist yet.
Displaying Statistics For a Single Port
In addition to displaying data for a set of ports, you can display historical data for an
individual port. You can select a port in one of two ways:
• Double-click on the data point for an individual port in the device or port group
statistics display (bar, datapoint, or pieslice inthe respectivechart,or row in a tabular
display).
• Click on a device, device slot, or port group in the left-side Component Tree to list the
ports it contains,then select a port.
A set of utilization statistics for the selected port is displayed, as shown in Figure 11-4.
